' To all whom it may concern:

i "This invention relates to a motor for effectively utilizing the force of the oceanwaves, the construet -ion'ibeing such that the motor automatically participates in =the eriodic floodzuid ehbof the waters and t at its. operation is continuously maintained 4 even a-fte 'r a;Wa e has expended its force and while the water is recedlng prior to the air rival of asrrcceedrng wave. e 'In the Accompanying drawing: Figure 1 is a plan \Z'iew of my improved wave r'njotor; ,Fig. 2 a cross section on line 3 a vertical section on :1 reduced scale on line 3+3, Fig.1, and Fig. i a detailof the bucket tilting means.

The wave motor comprises essentiilly n puir of ficats orpontoons 10 which support an intermediate casing 11 by means of a plulrulity -ef\ .inclined brzrees 12. Casing 11 comprises essentially pe'ir of parallel side plzites 13 a n'd-' is"gui'ded n its verticel tidal "ynoyeincnt n long e plurality ofstationary posts 14', Fig. 1 showing fgti'ifipf such posts. The latter are provided with nadir-l5 engaged by flanged Wheels 16 whieh itre fast orntriuisrerse shafts 17 journzrled in bearings Il otside plates-1'3.

'o'urnuled on o \-'e'rshot bucket Wheel 19 inounted on atrnnsvrrse shaftQO which '15 supported in suitable bearings 21,22 secured to side plates 13 unfl' pontoons 1O respecti'vely. A crank 2 formed on shaft .20 near one end thereof between the bearings 22 I carried lryfonlo of the pontoons' 10 is engaged by the pitnmn 2 of' a pump, cornpressor or other motionutilizing'device 25 to be driven by bucket Wheel 19, The latter is provided with a multitude of transversely extending peripheral pockets "'26 whirh may be closed at their ends at 27. Each pocket is .formed with a radially extending struightwull and with a curved wall 29,

- struck from the outer end of wall 28. v 1

At the culterendot ouch straight-wall 2-8,

there is located a transverse arbor -journuled iu'benrings 31 of wheel 19. Earth-M hor-30 passes tightly through thetubular hub or knuckle 52 ofan oscillutublo bucket Z'fikwhirh is 01' u shape and size to be snugly 2, Fig. 3,

as to here discharge a substantial body of I water and fill the uppermost ll'il'lCliBtsQ These means comprise a trough 39 secured to casing llat' a distance a-b'ov'ewheel19-well having a lower transverse discharge slot 40 located slightly'be'yond the wheel m art-the descending side of the wheeL- l lie- 'jeztside of: this trough is" prolonged--'downn; id to form an inelined deflecting pram-44 jextendsu-vith its lower end .to abeut the water level, and thus guides the w v ets and cause u qorrespoi-rding tu-i g of the wheel.

These rising huckols will grad-J ual-ly swing back into their pockets, the water being discharged therefrom as, soon as the buckets have been carried above the a water level. 'lVhen a bucket has thus been carriedto near the top of the wheel, it will have swung completely'into its pocket from which position it must be mechanically dist lodged, so that it will project beyondthe wheel periphery andpresent its open side 35 to the water descending through outlets 4'0 and 44. 'l-heJIneans for oscillating the buckets comprise a short arched rack 46 carried by'each side plate 13.near the rising top of wheel '19 and arranged concentrically to shaft 20. Each arbor carries at its end a pinion 47 adapted to engage said rack, so that when the bucket arrives at the point mentioned, its pinions will become temporarily engaged by the racks, so that it will be swung outward through an angle of-lSOdegrees and rest with its back 34' upon partito the top of the wheel at the rising sidetion '37. 'In this way-, the bucket will be swung clear of the wheel and. thus expose its open side to a fresh charge of descending on said shaft, a plurality of buckets hingedly connected. to said wheel, means also sup.- ported by the-float and located in proximity thereof for swinging the buckets outward, and means for directing the .waves toward the outwardly swung buckets.

2. A wave motor comprising a float, a

'horizontally disposed shaft rotatably 'supported thereby, an overshot wheel mounted onsaid shaft, a plurality of buckets hingedly connected to said wheel, means: also supported by the float and located in proximity to the top of the wheel at the rising" side thereof for swinging the buckets outward, a catch basin having an outlet above the wheel, and means for-directing the waves partly toward the outwardly swung buckets and partly to the catch basin.

3. A wave'motor comprisinga pontoen, a V

casing supported thereon, means for guiding the casing, an overshot wheel having peripheral pockets-and a shaft which is journaled. in the casing, a power-supplying device operated by the shaft, oscillatable buckets hinged to the wheel and adapted tofieng'age the pockets thereof, and means for swinging said buckets out of said; pockets at the rising side of the wheel:

4. A wave motor comprising a pontoon, a

casing supported thereon, means for guiding the casing, an overshot wheel having peripheral pockets and a shaft which is journaled in the casing, a power-supplying device opera-ted v,by the shaft, "oscillatable buckets hinged to the wheeland adapted to engage the pockets thereof, means for swinging said buckets outof said pockets at therising side of the wheel, and a catchbasin secured to the casing andhaving a discharge slot above the wheel.

-' 5. A wave motor comprising a pontoon, a'

casing supported thereon, means for guiding the casing, an overshot wheel having peripheral pockets and a shaft. which is journaled,

in the casing, a power-supplying glcyice op.-

eratcd by the shaft, oscillatable 'bucketshinged to the wheel and adapted to enga e the pockets'thereof, means for swinging said bucketsout ofsaid pockets at the risingside of the wheel, a' slotted. catch basin secured to the casing above the wheel and having an I inclined wave deflecting plate, and an in- 'clmedg ude plate located a distancev below said de'liecting plate. to form' an intervening chute having a discharge opening in prox- -'1-mity tothe to of the wheel. v l

6. A wave motorcomprising a casing, supporting pontoons .for said casing, an overshot wheel journaled in the casing and haying transversely extending peripheral pockets, sector-shaped buckets adapted to engage said pockets and liav-ingshafts that are journalcd in the wheel, pinions carried by tl eshafts, and curved racks on the casing that are adapted to be engaged by the pinions for. a limited period during each rotation of the wheel. 7
